The problem such as potential safety hazard, it is provided that a kind of lifting vehicle earthing of casing line apparatus.
Lifting vehicle earthing of casing line apparatus, including earth lead wheel disc, temporary grounding pole and earthing clamp, earth lead uses
The mode that single earth lead bilateral is wound around is wrapped on earth lead wheel disc, and the A end of earth lead is fixed with vehicle by earthing clamp,
Earth lead B end is connected with grounding body or ground stud by earthing clamp.
In this utility model, also include temporary grounding pole, when on-the-spot no ground body or ground stud, use temporary grounding pole
As interim earth point, described earth lead B end is connected by screw with the screw of temporary grounding pole.
Further, described temporary grounding pole material uses galvanizing round steel.
Further, the size of described earthing clamp is changed according to type of vehicle, and detachably.
The beneficial effects of the utility model:
One, this utility model uses temporary grounding pole, solves electrical construction operation field and usually looks for less than earth point,
Cause the problem that earth lead cannot be carried out ground connection.
Two, the multiple earthing clamp of the replaceable use of this utility model, for different lifting vehicles, on-the-spot different ground connection
Point, all can meet on-the-spot actual requirement.
Three, the earth lead on the earth lead wheel disc in this utility model, the mode using single earth lead bilateral to be wound around, make
It is time saving and energy saving that earth lead possesses execute-in-place, and possesses portable feature.
Four, termination scene described in the utility model is carried more convenient.Can be for different lifting vehicle, existing
Field carries out ground connection.Earth lead is the most at random, meets the requirement of standardization job on-the-spot.

Detailed description of the invention
Detailed description of the invention one, combine Fig. 2 to Fig. 6 present embodiment, lifting vehicle earthing of casing line apparatus, this dress are described
Putting and include earth lead wheel disc 1, temporary grounding pole 2 and earthing clamp 3, the mode that earth lead uses single earth lead bilateral to be wound around twines
Being wound on earth lead wheel disc 1, earth lead A end is fixed with vehicle by earthing clamp 3, and earth lead B end passes through earthing clamp 3 and connects
Terrain or ground stud connect.
Also including temporary grounding pole 2 in present embodiment, institute, when on-the-spot no ground body or ground stud, uses temporary grounding
Pole 2 is connected by screw with the screw of temporary grounding pole as interim earth point, described earth lead B end.Described temporary grounding
Pole 2 material uses galvanizing round steel.
The size of the earthing clamp 3 described in present embodiment is changed according to type of vehicle, and detachably.
In conjunction with Fig. 2, Fig. 3 and Fig. 4, present embodiment being described, in Fig. 3, earth lead wheel disc arranged on left and right sides is earth lead, right side
Earth lead B end is relatively short circuit ground termination ground wire (B end is for connecting copper cash nose), left side ground line A end more a length of lifting vehicle side joint
Ground wire (A end is for connecting copper cash nose).Temporary grounding pole in Fig. 4, according to " electric device installing engineering grounding device is constructed and tests
Receive specification " " the grounding body end face depth of burying should meet design code to 3.3.1 clause regulation.When no standard, it is no less than
0.6m." and scene carry the whether factor such as convenient, finally determine the most a length of 0.9m of temporary grounding.Ordinary circumstance, on-the-spot without connecing
Pile, grounding body, use temporary grounding pole.And the F end (F end is connecting screw hole) of temporary grounding pole and earth lead B end in Fig. 3
It is joined directly together, and is attached by M10 screw.
In conjunction with Fig. 5 a, Fig. 5 b and Fig. 5 c, present embodiment being described, wherein, the earthing clamp in Fig. 5 a is applicable to lifting vehicle
With ground side both sides, laying particular emphasis on thicker cylindrical reinforcing steel, connecting screw C can earth lead A, B two ends all can direct phase in Fig. 3
Even, and it is attached by M10 screw.And the size of the earthing clamp in Fig. 5 a can change according to vehicle model, equally
Being applicable to lifting vehicle and ground side both sides, but lay particular emphasis on bar shaped grounding body, in connecting screw also Fig. 3, earth lead A, B two ends are equal
Can be joined directly together, and be attached by M10 screw.
The structure of the earthing clamp in Fig. 5 b is equally used for lifting vehicle and ground side both sides, but lays particular emphasis on cylindrical steel
Muscle, connecting screw D point all can be joined directly together with earth lead A, B two ends in Fig. 3, and is attached by M10 screw.
The structure of the earthing clamp in Fig. 5 c is only applicable to ground side, it is adaptable to five-defence block ground stud grounding body, E
End (E end is connecting screw hole) is only joined directly together with earth lead B end in Fig. 3, and is attached by M10 screw.
Detailed description of the invention two, combining Fig. 6 present embodiment is described, present embodiment is described in detailed description of the invention one
The installation method of lifting vehicle earthing of casing line apparatus, the idiographic flow of the method is:
One, position chosen by lifting vehicle, puts down support before also not lifting by crane.First the scene of searching have, without fixing grounding body or
Ground stud；
Two, when no ground body or no ground stake, should first select high-quality, soil face on the spot, use sledgehammer around place
Ground stud is squeezed under soil more than 60 centimetres.Then by earthing pole g end (g end is connecting screw hole) and Fig. 3 of temporary grounding pole
Middle earth lead B end is joined directly together, and A end selects earthing clamp to be attached according to type of vehicle.
It is not required to when having ground stud use temporary grounding pole, by the earthing clamp directly and in Fig. 5 c of the earth lead B end in Fig. 3
Screw connects, and earth lead A end, according to field vehicle type, selects suitable earthing clamp to fix.
No ground stake, when having grounding body, selects suitable earthing clamp to be directly connected with earth lead B end in Fig. 3, A end root
Suitable earthing clamp is selected to be attached according to type of vehicle.
Three, being fixed respectively by the earthing clamp at earth lead two ends, car body contact site must be the metal covering not painted.
After carrying out above measure, driver just can get on the bus operation suspension bracket.
Lifting vehicle earthing of casing line apparatus described in present embodiment, in lifting vehicle operation, just in case high-voltage line pair
Hanging the electric discharge of (bucket) arm or hang (bucket) arm and touch circuit and conduct electricity, failed shorted electric current I flows to greatly through vehicle body by earth lead,
Make whole car body keep isoelectric level with the earth, greatly reduce the electric power impact to human body.Get on and off driver, and ground is helped
Lifting goods personnel, other near the personnel of car body, does not have the danger shocked by electricity by powerful contact voltage, can alleviate fatal
Threaten, thus reduce the injures and deaths of personnel.Meanwhile, earth lead dispersion has been walked by the big electric current of the fault of wheel, can avoid because of tire
Blast, catch fire and the fire hazard that causes, reduce the loss of property.
